A critical operation is planned for later today. What preparations can I make within Verify-QC? After changing the L-band beam my RTCM station list is not fully populated, why is this? Does Verify-QC configure all my LD2/LD2S settings or are some manual entries required? How can I obtain a manual for Verify-QC v1.20? How do I add non-VERIPOS RTCM stations to the Verify-QC software? How do I archive data in Verify-QC? How do I check the version number of my Verify QC software? How do I configure an NTRIP RTCM input in Verify QC? How do I configure Verify QC to compute an Apex (Apex2) solution How do I configure Verify QC to compute an Ultra or Ultra2 solution? How do I extend the duration of or upgrade my Verify-QC dongle? How do I log RINEX data using the Verify-QC software? How do I setup Apex as backup within Verify QC? How do I upgrade my verify QC? How to Import Verify QC Config Files from a USB to an LD6 If I have too many windows open in Verify-QC, could this cause my computer to crash? I have rebooted my LD2, connected to Verify QC using the Ethernet Port and GNSS Rx in Calculation Status has turned red and stayed red. How do I get it green again? Tides - Can I change between Ultra and Apex? Tides - Can I use the Tides information in real-time? Tides - (How) does the Tides calculation compensate for Heave, Pitch and Roll? Tides - How do I configure and View Tides in Verify QC? Tides - How do I convert from MSS Tides to LAT? Tides - How do I know that MSS Tide and Geoid Tide give representative results? Tides - How do I know that the Tides calculation is giving continuous results? Tides-If I restart QC does Tides restart? Tides - We are leaving the work area to make a port call, should I reset Tides? Tides - What Antenna Height should be measured and what accuracy is required? Is this value fixed for the duration of a survey or should it be updated? Tides - What is the vertical reference for the VERIPOS Tides estimates? Tides-When will tides reset? Tides - Where can I find the Tides logging files? Verify-QC for LD6 Version User Manual Verify-QC v1.20 User Manual We have moved to a new area. Why am I not receiving corrections in Verify-QC? What are the new features of Verify-QC v1.20? What are the recommendations concerning Ultra Backup Positions in Verify-QC? What Geoid model is used within the Verify-QC software? What GNSS receivers does the Verify-QC software support? What is the current release verison of the Verify-QC software and where can I get a copy? What is the minimum specification for a PC to run Verify-QC? Is Windows Vista or Windows 7 supported? What is the purpose of the Tides function in Verify-QC? What is the Vio application included with Verify-QC and how can I use it? When I try to start Verify-QC, I receive a warning message about the dongle. What can I do? Why am I not receiving all the expected reference stations in Verify-QC? Why can’t Verify-QC compute an Ultra Position? Why is “Config” missing from my main menu in Verify-QC? Why is one section of the RINEX logging menu of Verify QC greyed out?

Tides - How do I know that the Tides calculation is giving continuous results?

Any gaps or resets in the Ultra/Apex PPP solution will cause gaps in the ‘Tidal Height’ and the ‘Geoid Tide’ plots:

Any gaps or resets in the Ultra/Apex PPP solution will cause gaps in the ‘Tidal Height’ and the ‘Geoid Tide’ plots

And gaps in the TideInfo.txt file:

Longer gaps will also have an impact on the hourly Doodson calculation creating the MSS reference:
